SPPattern* SPPattern::shown

private

The pattern at the end of the href chain, currently tasked with keeping our DrawingPattern up to date.

When 'shown' is deleted, our DrawingPattern will be unattached from it and 'shown' will be nulled. Later (asynchronously), 'shown' will be re-resolved to another Pattern and our DrawingPattern will be re-attached to that.
